There's not enough information about this to be excited for it yet. Halo 2 Anniversary is basically a guarantee, but I can't think of how it would logically fit inside this cumpilation. A single disk containing a Halo 1 Anniversary port, Halo 2 Anniversary, a Halo 3 port, and a Halo 4 port probably makes the most sense, but where does that leave H1A's Reach multiplayer if Reach isn't included? Do they just cut it completely so that Halo 1 Anniversary 2 is just the campaign? Could they re-add Halo 1's original offline multiplayer? Do Halo 3 and Halo 4 keep their online multiplayers? Wouldn't that detract from the significance of Halo 2 Anniversary? Will Cocop ruin this too? So many questions...

If they release a compilation of 4 games, I just can't see them including multiplayer for just H2, which means:

1) they will release multiplayer for all games (which would divide the player base and be a lot of work)

2) they will release multiplayer for none of the games (i could see this happening)

3) they will release multiplayer from 4

I might be too sure of this, but I don't think H2 multiplayer is happening. Would love to be wrong, and getting all 4 single player games would be nice, but it isn't as exciting as the H2A idea was to me.

It seems like a death sentence for one of the games to release two multiplayer Halo's with online at once. It's either going to be Halo 2, or nothing at all, I think. No one would ever buy any more video games ever if they did both.

I can only see Halo 2's multiplayer being included also. Halo 1 was "kinda" included with Reach, and we already have existing online multiplayer with 3 and 4 (lol). Microsoft could do something proactive though - if 3 and 4 also had multiplayer, they could include cross-platform play with their 360 counterparts (PC too?).

How about we bet that this game has all of the multiplayer? Let's go for $20.

Are you making bets using insider knowledge that you've received from a specific individual? Because if so, I don't think that's fair. Based on Microsoft's and 343's track records, it doesn't make any logical sense for them to add Halo 1's original multiplayer back into a re-re-release, and including Halo 2, 3, and 4's multiplayer on one disk would completely contradict 343's stance on "not wanting to fracture the Halo playerbase." These things, they make no sense, but you seem extremely confident that they will happen. I'm onto you, Jironimoo...
